Torrents aren't that convenient anymore. The vast majority of available data is on private trackers, and the procedures for joining said trackers are extremely byzantine, sometimes outright demeaning, and require vast quantities of time and effort. I'd argue that it's much more convenient to just pay Bezos, unless - as suggested - you're a teenager and don't have any money, or the rightsholders made it impossible for you to make the purchase (this has happened to me when trying to purchase music, of all things).
